Abstract 1. A PROCESS FOR PREPARING A STABLE PROMOTER SOLUTION WHICH COMPRISES FIRST DISSOLVING IN AN AQUEOUS PHOSPHORIC ACID SOLUTION AT LEAST ONE COMPOUND OF A GROUP VIII METAL SELECTED FROM NICKEL HYDROXIDE, COBALT HYDROXIDE, NICKEL CARBONATE, COBALT CABONATE, NICKEL ACETATE, COBALT ACE TATE, NICKEL FORMATE, COBALT FORMATE, AND NICKEL OXIDE, SAID NICKEL OXIDE IN ITS SOLID FORMATE, AND NICKEL OXIDE OF A LEAST ONE SQUARE METER PER GRAM, AND THEN DISSOLVING MOLYBDIC OXIDE IN THE RESULTING SOLUTION BY HEATING AT A TEMPERATURE OF ABOUT 85*C. TO REFLUX UNTIL COMPLETE DISSOLUTION OF MOLYBDIC OXIDE OCCURS TO PROVIDE FROM ABOUT 0.3 TO 2.5 MOLES PER LITER OF PHOSPHORUS, FROM ABOUT 0.4 TO 1.5 MOLES PER LITER OF SAID GROUP VIII METAL, AND FROM ABOUT 1 TO 3 MOLES PER LITER OF MOLYBDENUM THEREIN.
